Can you imagine in your local shopping mall, when you step into an elevator and find a giant hole in the middle of it? No kidding! South side shopping centre in London tricked people into thinking that the floor of the elevator has collapsed with the awesome 3D illusion, created by artist Andrew Walker. This 3D Illusion was created to prepare the British public for the launch of Alton Towers Resort’s new attraction – Nemesis Sub-Terra. The ride, described as “a psychologically and physically thrilling experience,” takes visitors on an underground journey through an elaborate network of caves. Really smart campaign! [source].
